Patent JP-H04151267-A (JP)
Title: Led array
Inventor: NANAO TSUTOMU
IPC: H01L25/075
Filed: 1990-10-15
Abstract: PURPOSE:To miniaturize the above LED array by a method wherein a condenser lens is made of transparent resin in aspheric shape by injection molding method. CONSTITUTION:Both of incidence side surface 14 and emission side surface 15 of a condenser lens 15 are aspherical, and the radius of curvature is bigger on the incidence side surface 14 than the emission side surface 15. The emission side surface of this condenser lens 13 is formed in such that the lens surfaces 16 and 16 on both ends in the longitudinal direction are smaller in radius of curvature than the lens surface 17 at the center. As the radius of curvature is bigger on the incidence side surface 14 than that on the emission side surface 15, the total reflection on the incidence side surface 14 can be prevented, not only making the condensing efficiency for the light emitted from an LED chip 12 increased, but also making the focal distance to a copy on the emission side shortened. As the radius of curvature on the lens surfaces 16 and 16 on both the ends in the longitudinal direction is smaller than that on the lens surface 17 at the center, the opposite side ends of a linear light applied to the copy are brought close each other, making compensation for the decline of illuminance in this part possible. Therefore, the condenser lens 13 can be made compact and thin without sacrificing condensing efficiency of the lens.

Title: Parallel type analog/digital converter
Inventor: KAGAWA MINORU
IPC: H03M1/36
Filed: 1990-10-15
Abstract: PURPOSE:To attain high speed and high accuracy by using a single differential amplifier so as to amplify a reference voltage and a converted input voltage differentially and discriminating its output with plural latch type comparators operated by clocks whose phases are different so as to output a digital discrimination output. CONSTITUTION:For example, 256 circuits of comparator sections 2 are provided, each of which discriminates whether or not an analog converted input voltage Vi belongs to a specific gradation to the A/D converter and the analog converted input voltage Vi is inputted to an input line 1 and fed also to other comparator sections 2. Since the differential output of a single differential amplifier 4 or 5 is applied to plural latch type comparators 6, 7 comparing and discriminating the quantity of the analog converted input voltage Vi, latching the result and giving a digital output, unarrangement of offset voltages of the comparator section 2 viewed from the input line 1 receiving the analog converted input voltage Vi is avoided. Thus, the high speed and high accuracy parallel type A/D converter is realized.

Abstract: PROBLEM TO BE SOLVED: To provide a multilayer semiconductor diode having a novel structure. SOLUTION: In a light emitting element having a single layer light emitting layer, the light emitting layer is sandwiched by a first quantum wave interference layer comprising first layers and second layers having a wider band width than the first layer laid in layers at a multiplex period, and a second quantum wave interference layer comprising third layers and fourth layers having a wider band width than the third layer laid in layers at a multiplex period. The first quantum wave interference layer serves as an electron reflective layer by setting the wavelength of electrons injected to each layer equal to odd times of the quarter of wavelength of quantum wave and the second quantum wave interference layer serves as an electron transmission layer by setting the wavelength of electrons injected to each layer equal to even times of the quarter of wavelength of quantum wave.  Emission efficiency of the emission layer can be enhanced by setting the wavelength of electrons equal to odd times of the quarter of wavelength of quantum wave. Emission efficiency of the pairs of electron and hole in the emission layer can be enhanced furthermore by forming a thick barrier wall at the boundary of the emission layer and the first and second quantum wave interference layers, respectively.
